Description

TECHNICAL FIELD

[0001] The present application relates to the mains power switch electronic technology in the electronic field, and particularly to a room automatic power-off system. BACKGROUND

[0002] At present, in some public places, such as hotels, guesthouses and inns, it is necessary to control the power supply of the guest rooms so as to avoid the waste of electricity. The device used for the power supply control of the guest rooms is a card insertion power switch. When the guest inserts the door lock card into the card insertion power switch, the power supply of the room is turned on. When the guest takes out the door lock card, the power supply of the room is automatically turned off after a time delay. If the guest leaves the room without taking out the card, the guest cannot open the door when returning. Thus, the guest is forced to take out the card and leave the room, and the purpose of turning off the power supply when the guest leaves is achieved. The precondition for using the card insertion power switch in the guest room is that the card insertion door lock must be installed.

[0003] With the technical progress of the door lock, more and more new types of door locks appear, such as the fingerprint lock, the face recognition, the mobile phone card insertion lock and the like. The card insertion power switch cannot be used for these new types of door locks. The control of the power supply of the guest room becomes a problem. The automatic power-on switch device of the room in the original patent of the present inventor, the patent number of which is ZL 200920206339.1, can solve the problem of the control of the power supply of the guest room without the card insertion door lock. However, since the automatic switch mainly uses the thermal release infrared human body detector, the detector is extremely sensitive to the environmental changes, and it is difficult to achieve absolute reliability. Thus, the false alarm or the missed alarm phenomenon cannot be avoided, and the installation technology is also required to be high. Therefore, the practicality is poor. SUMMARY

[0004] The purpose of the present application is to provide a room automatic power-off system which is not limited by the type of the door lock and is not affected by the environment. The system is composed of a power supply control switch, a door magnetic detector and a manual button. The power supply control switch is installed in the distribution box of the room, and controls the on-off of the power supply of the room and the mains. The door magnetic detector is composed of a magnetic sensor and a permanent magnet, and is installed on the door frame and the door panel of the room, respectively. The manual button is installed on the wall in the room. The door magnetic detector and the manual button are connected with the power supply control switch, respectively. When the person opens the door, the magnetic sensor of the door magnetic detector is separated from the magnet, the door magnetic detector sends the opening door signal to the power supply control switch, and the power supply control switch supplies the power to the room. When the person closes the door, the magnetic sensor of the door magnetic detector approaches the magnet, the door magnetic detector sends the closing door signal to the power supply control switch, and the power supply control switch delays the power-off of the room. The power supply control switch sends the sound of the power-off in the delay power-off. If there is no one in the room, the power is automatically turned off after the time delay. If there is someone in the room, the manual button is pressed, the manual button sends the button signal to the power supply control switch, and the power supply control switch stops the delay and the power-off or restores the power supply if the power has been turned off. Thus, the purpose of the control of the power supply is achieved.

[0005] To solve the technical problems of the present application, the present application discloses a room automatic power-off system, comprising a power control switch, a door magnetic detector and a manual button, the door magnetic detector and the manual button are connected with the power control switch respectively, wherein:

[0006] The power control switch is connected with the power line and the room appliance power supply line respectively, and is used for controlling the power on and off of the power line and the room appliance power supply line;

[0007] The door magnetic detector is used for monitoring the opening and closing of the door, and transmits the opening and closing information to the power control switch, so that the power control switch supplies power to the room or cuts off the power;

[0008] The manual button is used for transmitting the pressing information of the person to the power control switch, so that the power control switch supplies power to the room.

[0009] Preferably, the door magnetic detector is connected with the power control switch by wired connection or wireless connection.

[0020] The present application discloses a room automatic power-off system for room power control.

[0021] Figure 1 Connection diagram of the room automatic power-off system of the preferred embodiment of the present application. The automatic power-off system comprises a door magnetic detector 11, a power control switch 12 and a manual button 13. The door magnetic detector 11 is composed of a magnetic sensor and a permanent magnet, which are respectively attached to the door frame and the door panel of the room door. The power control switch 12 is installed in the distribution box of the room, and is connected to the power supply line and the room appliance power supply line respectively, for controlling the room power on and off. The manual button 13 is installed on the wall in the room, for manual operation by the person in the room.

[0022] The connection of the door magnetic detector 11 and the power control switch 12 and the connection of the manual button 13 and the power control switch 12 of the embodiment all adopt wireless communication mode, and the wireless signal is composed of address code and data code. The working power of the power control switch 12 is provided by the power supply, and the door magnetic detector 11 and the manual button 13 are powered by batteries.

[0023] Figure 2 Schematic diagram of the power control switch 12 Figure 1 The schematic diagram of the power control switch 12 of the preferred embodiment of the present application is composed of a single-chip microcomputer control circuit 21, a wireless receiving circuit 22, an address coding circuit 23, a relay switch 25 and a buzzer 24. When the wireless receiving circuit 22 receives the signal, the signal is sent to the single-chip microcomputer control circuit 21. The single-chip microcomputer control circuit 21 checks the address code of the received signal through the address coding circuit 23, and if it is confirmed that the address code is the address code of the room, the signal data code is processed, and the relay switch 25 is processed for on and off. The 26 arrow mark is the power supply input, and the 27 arrow mark is the power supply to the room. If the data code is power-off, the single-chip microcomputer control circuit 21 delays power-off, and drives the buzzer 24 to sound to remind the person in the room to operate the manual button 13.

[0024] Figure 3 Schematic diagram of the manual button 13 Figure 1The schematic diagram of the door magnetic detector 11 shows that it consists of a microcontroller circuit 31, a Hall effect circuit 32, an address encoding circuit 34, and a wireless transmission circuit 35. 33 is a permanent magnet. The Hall effect circuit 32 and the magnetic piece 33 are respectively attached to the door frame and the door panel. When the door is opened, the Hall effect circuit 32 separates from the magnetic piece 33; when the door is closed, the Hall effect circuit 32 approaches the magnetic piece 33. Based on the changes in the Hall effect circuit 32, the microcontroller circuit sends a signal containing an address code and a door open or closed data code to the wireless transmission circuit 35, thus activating the wireless transmission circuit 35 to transmit the signal.

[0025] Figure 4 This is a preferred embodiment of the present invention. Figure 1 The schematic diagram of the manual button 13 shows that it is a touch switch composed of a microcontroller circuit 41, a touch circuit 42, an address encoding circuit 43, and a wireless transmission circuit 44. When a person touches the sensing area of ​​the touch circuit 42, the touch circuit 42 is triggered. The microcontroller circuit 41 receives the trigger signal and sends a signal containing the address code and power transmission data code to the wireless transmission circuit 44, thus activating the wireless transmission circuit 44 to transmit the signal.

[0026] The working process of the automatic power-off system in this room is as follows:

[0027] When the door opens, the Hall circuit 32 of the door magnetic detector 11 separates from the magnet 33, and the Hall circuit 32 loses magnetization. The microcontroller circuit 31 receives this signal and determines that the door is open. It then reads the address code from the address encoding circuit 34 and activates the wireless transmission circuit 35 to transmit a signal. This signal consists of the room's address code and the door opening data code. After the wireless receiving circuit 22 of the power control switch 12 receives the signal, the microcontroller control circuit 21 reads the address code from the address encoding circuit 23 for address verification. Once it confirms the address is the room's, it activates the relay switch 25 to supply power to the room based on the door opening data code signal.

[0028] When the door is closed, the Hall circuit 32 of the door magnetic detector 11 approaches the magnet 33, magnetizing the Hall circuit 32. The microcontroller circuit 31 receives this signal and determines that the door is closed. It then reads the address code from the address encoding circuit 34 and activates the wireless transmission circuit 35 to transmit a signal composed of the room's address code and the door-closing data code. After receiving the signal, the wireless receiving circuit 22 of the power control switch 12 reads the address code from the address encoding circuit 23 for address verification. If the address is confirmed to be the room's address, a delay is initiated based on the door-closing data code signal. During this delay, the buzzer 24 sounds to alert the person inside. If an open signal or a manual touch signal from the manual button 13 (also indicating the room's address code) is received during the delay, the delay is cleared and the buzzer 24 stops, maintaining power to the room. If no such signal is received, the buzzer 24 stops sounding after the delay, and the relay switch 25 is activated to disconnect the room's power.

[0029] When the touch circuit 42 of the manual button 13 senses the touch of a person, the single-chip microcomputer circuit 41 receives the signal and reads the address code of the address coding circuit 43, and starts the wireless transmitting circuit 44 to transmit a signal composed of the address code of the house and the touch data code. After the wireless receiving circuit 22 of the power supply control switch 12 receives the signal, the single-chip microcomputer control circuit 21 reads the address code of the address coding circuit 23 to make an address check, and after confirming that it is the address of the house, starts the relay switch 25 to supply power to the room according to the touch data code signal. If the power supply control switch 12 is in the time-delay power-off state, the time delay will be cleared and the buzzer 24 will stop sounding, and the room will be kept powered.

[0030] In summary, the automatic room power-off system disclosed in the present application is composed of three devices, i.e. the power supply control switch 12, the door magnetic detector 11 and the manual button 13. The power supply control switch 12 is installed in the room distribution box to control the power supply of the room, the door magnetic detector 11 monitors the opening and closing of the room door, and the touch switch of the manual button 13 starts the power supply in the room. Since all the devices use wireless communication, wiring is not needed, and the installation process is simplified. Since all the devices work in the on-off state, control errors are eliminated, and reliability is ensured. Compared with the current card-insertion power-on switch of the guest room, the system is not limited by the type of door lock, and can solve the power supply control of all guest rooms.
